Other Calibers
The same basic weapon was also chambered for the British .303 round, and was used as a basic fighter aircraft gun in fighters such as the Supermarine Spitfire until the widespread introduction of the larger caliber Hispano-Suiza HS.404 cannon, and throughout the war in bombers.
Similar versions for a variety of European calibers were delivered by the Belgian gun maker FN (Fabrique Nationale), notably German-standard 7.92 Mauser which was widely used in Eastern Europe; and by Swedish gun maker Carl Gustaf SGF in 6.5x55mm and 8x63mm calibers.
Argentina used Colt-manufactured guns chambered for the standard Argentine 7.65mmx53 cartridge.
US-manufactured M1919s were converted to the 7.62mmx54R cartridge by both the People's Republic of China and North Vietnam in order to use captured guns with their standard machine gun ammunition. The standard links and belts for the M1919 were retained. Similar conversions are available on the US commercial market for recreational shooters to take advantage of cheap surplus 7.62mmx54R ammunition.
